Dec-31-05		Werewolf: It's a difficult to find combination and black's 30. Bh2+ is so subtle and fine... :)

Dec-31-05		witty: will someone pl. show the later moves leading to mate, as i m not able to understand it, may be i m missing something.

Dec-31-05		WannaBe: 32. Kh1 (it's the only square.) g3 33. Rf2? Qh2#

Dec-31-05		HannibalSchlecter: witty, I hope this helps: Black first created a weakness in the pawns that were protecting the king by playing (24) Nxg2, on the next move black took advantage of the pin on the king and played (25)g4 to help break open the position and give the queen a support post (notice the f pawn can't capture because it would be in check) (26)Next move black crashes through with the queen and gives check. (27) Now here black eliminates some of the defenders of the king and plays RxB, and after the knight recaptures the (28) Queen takes the knight with check keeping the attack going with 2 less white pieces in the way to interfere with her plans. Next (29) another queen check drives the king to a more vulnerable square so the bishop can sacrifice itself to give check in order for the queen to occupy a more dangerous square as the king is driven to the corner(30)After the queen checks on f2 (31) white resigned because the idea of pawn to g3 and Qh2 mate is unstoppable.

Dec-31-05		al wazir: Regarding the opening, I think Alekhine is getting too much credit here. Nimzovich's Defense (not to be confused with the NID) is 1. e4 Nc6 2. d4 d5. One line continues 3. Nc3 Nf6 4. exd5 Nxd5 5. Nxd5 Qxd5 6. Nf3 Bg4 7. Be2 O-O-O 8. c3, transposing into the present game. This is one of my favorite openings.

Dec-31-05		ramprasad2: can the white king escape with 30 Ke1 instead of 30 Kg1?

Dec-31-05		erimiro1: < al wazir: This is one of my favorite openings> As black? No one plays it for ages because it looks like a bad variant of the French (black has to waste time, by move again his knight from c6, to play c5). The variant you've mentioned seems to be good for black, and as I wrote earlier, I don't think that N:N etc. is good for white.

Dec-31-05		al wazir: <ramprasad2: can the white king escape with 30 Ke1 instead of 30 Kg1?> 30. Ke1 Re8+ 31. Kd2 Bf4+ 32. Kc2 Re2+ 33. Rd2 Rxd2+ 34. Kc1 Qd1#.

Dec-31-05		al wazir: <erimiro1: < al wazir: This is one of my favorite openings> As black? No one plays it for ages> I've revived it. It gives black some initiative and avoids openings my opponent knows better than I do (which includes almost all openings).

Dec-31-05		netlava: I stopped looking after I found ...g4 because I guessed that black will somehow find mate... but that's not true since I don't think I would have found Bh2+!

Dec-31-05		DAL9000: <After 31...Qf2+ 32.Kh1 g3 33.Rd2 g2+ 34.Kh2 g1=Q+ 35.Kh3 Qg4++> Uh, dude, that may or may not work, but the point of 31... Qf2+ is that, after 32. Kh1 g3, mate on h2 is inevitable. If 33. Rd2, Qxd2 works fine.

Dec-31-05		crafty: 24...g4 25. ♕a2 ♘xf3+ 26. gxf3 ♕xf3 27. h4 ♗f4 (eval -4.38; depth 12 ply; 500M nodes)

Dec-31-05		aginis: ok someone enlighten me why not 10...Nxd4 to win a pawn.

Dec-31-05		brainzugzwang: <DAL9000> I think the point of syracrophy's 33.Rd2 is to prevent 33...Qh2#, and after 33...Qxd2, 34.Qg1 seems to let White hold on for a few moves, although he's a couple pawns down and in tough shape after 34.Qg1 Re8 followed by Re2, I'd say. Anyway, syracrophy's forced mate seems best (duh!).

Dec-31-05		brainzugzwang: I was also thinking the win had to be in 24...Nxf3 25.gxf3 Qxf3 followed by ...g4. Does that amount to basically a transposition from the game line?

Dec-31-05		Cogano: <Mating Net> & <WannaBe> I would really appreciate it if you would extrapolate the mate you elude to. & <WannaBe> If White plays Rd2, as you say, then Black can't mate with Qf2#, for there's nothing preventing White from playing Rxf2! Thanks a bunch. Happy New Year to one and all! Cheers!

Dec-31-05		aginis: Brainzugzwang> 33.Rd2 g2+!! 34.Kh2 35.g1=Q++ Kh3 36.Qgg2# or Qgg3#, Qg4#, Qgh2#, Qfg3#, Qf3#, Qe3#.

Dec-31-05		HannibalSchlecter: aginis, I don't see how 10. Nxd4 wins a pawn.

Dec-31-05		kevin86: I prefer the simple finale; 32♔h1 g3} and the death sheet can be pulled down on the white king.

Dec-31-05		WannaBe: <Cogano> You are talking about a post that I have deleted after I posted it, I realized the line was wrong and have since deleted it. It was posted before <al wazir>'s post. If you are referring to the post that still exists, there is no Rd2. =)

Dec-31-05		dr.noooo: I toyed with knight taking at f3 and getting three pawns for the piece: only after another look did the sac at g2 hit me with the notion of breaking through with the pawns, pinning the king. After that the rest of it was easy enough, but over the board I have no doubt I would have missed the sac. It always helps KNOWING the key move is right before your eyes. Tal made a fair living with just this kind of sac, probably more than anybody ever, turning his pawns into pieces.

Dec-31-05		Cogano: <WannaBe> Thank you for the clarification & I regret the misunderstanding. I hope there's been no incon- venience. Happy New Year. Cheers!

Jan-04-06		patzer2: Black's amazing demolition of pawn structure combination 24...Nxg2! to defeat a future U.S. Champion actually began a move earlier with 23...Nh4!! Here's a detailed analysis with Fritz 8: <1. e4 Nf6 2. Nc3 d5 3. exd5 Nxd5 4. Nxd5 Qxd5 5. d4 Nc6 6. Nf3 Bg4 7. Be2 O-O-O 8. c3 e5 9. O-O exd4 10. cxd4 Bd6 11. Be3 Kb8 12. h3 Bd7 13. Qc2 f6 14. a3 Rde8 15. Rfd1 Ne7 16. Qc4 Bc6 17. Qc1 g5 18. Ne1 h5 19. Bf3 Qf5 20. Qb1 Bxf3 21. Nxf3 Qd5 22. Nd2 Nf5 23. Nf1 Nh4!! 24. f3 Nxg2! 25. Kxg2 g4! 26. h4> If 26. hxg4, then Black wins after 26...hxg4 27. Nd2 (27. Qc2 Qxf3+ 28. Kg1 Rh1#) 27... gxf3+ 28. Kf1 (28. Kf2 Rh2+ 29. Kf1 Qg8 30. Nxf3 Qg2+ 31. Ke1 Qe2#) 28... Rxe3 29. Qg6 Rh1+ 30. Kf2 Re2#. <26... Qxf3+ 27. Kg1 Rxe3 28. Nxe3 Qxe3+ 29. Kf1 Qf3+ 30. Kg1> If 30. Ke1, then Black mates after 30...Re8+ 31. Kd2 Re2+ 32. Kc1 Qf4+ 33. Rd2 Qxd2#. <30... Bh2+! 31. Kxh2 Qf2+> 0-1 White resigns in lieu of 32. Kh1 g3 33. Rd2 g2+ 34. Kh2 g1=Q+ 35. Kh3 Qgg2#

Jan-14-06		Cogano: <patzer2> Hi. According to Fritz8's analysis, which you kindly posted, if If 26.hxg4, then Black wins after 26... hxg4 27.Nd2 (27.Qc2 Qxf3+ 28.Kg1 Rh1#) 27... gxf3+...What I want to know is if you can at least give me your opinion as to why play 28.Kf1 rather than 28.Nxf3? Thanks & have a good day. Cheers!

Feb-10-06		patzer2: <Cogano> After 26.hxg4 hxg4 27.Nd2 gxf3+ , White will be mated. The move 28. Kf1 (mate-in-six) delays the mate a bit longer than 28. Nxf3 (mate-in-four). One mate with this line is 26.hxg4 hxg4 27.Nd2 gxf3+ <28. Nxf3> Rh2+! 29. Kg1 Qxf3 30. Qg6 Rh1#.
